they run cooler than the 300s

thats why 300s have them.

Ill fined the mnumbers for u now POS

So its not going to be over cooled as the oil is flow is restriced to around the engine until up to a working temperature also it will diverts the oil to the cooler when it becomes too hot which combined with the Landy cooler will bring the temperature back to a cooler state as designed. I suppose it could be argued that this increased flow through the oil pipes looped up together could help cool itself slightly acting as a kind of rad but I would suspect it wouldn't be that much cop

Nice one, thank you very much

Yeah, it's effectively there to ensure that your oil maintains its 'peak' operating temperature for the engine. Not too hot (thin), not too cold (thick). If you give your engine some work, say pulling large loads up hills, the thermostat will open and keep the oil at the right temperature. I can see no harm what so ever in having an oil cooler connected, and I plan on doing so, this weekend possibly. I will check to see whether or not my old 2.5 N/A filter housing has a thermostat though, I might be swayed not to if the oil is going to be cooled constantly.

As for the pipes themselves, any surface with a direct contact to air / moving air will transfer kinetic energy - cooling the oil. Obviously the aluminium finns on a radiator dissipate heat more effectively than rubber pipes.

Here is the oil filter housing thermostat:

It fits all four cylinder diesel engines, so I take it that the N/A, TD, 200TDi and 300TDi all use the same stat.

Been spending this afternoon on Spitfiremk1uk's series build and almost finnished off my poxy tow hitch. Ah fitted up his newly delivered galv bulkhead having a blonde day. Working out what intercooler oil cooler and rad to use on his 1961 IIa. Defo need an oil cooler even in the UK my engine temp got quite high laning in Derbyshire last year. Although the thermostat will try and save the oil thinning and breaking down I wouldn't fancy it not being cooled at all. The series its a muct as the mota might be heading to Morocco and down Africa for a jolly when its finnished knowing Spitfiremk1. Thats a jolly I'd quite fancy going on myself.

I'm tempted to change my thermostat for the cost of them TBH.

sypher · May 14, 2010

right acording to Microcat mine should not have them lol , BUT

From chassis number FA389799 to LA939975 it does ( Mine is AA - go figure ? )

Anyway
Oil filter housing to pipe coupling NRC8618 cradocks want £7 each for em Fook me not at that price for a male - male pipe coupling .....

Pipes
top NTC2927
bottom NTC2928

I cant beleave that there £47 each ------- your best bet is get round the scrappys or the bay .

Plz dont quote me on them numbers as microcat says there not for my chassis number when I do actually have them ..... but its a start

I'd test your existing thermostat before you buy a new one. I don't know what temperature they're supposed to open at, but I'd imagine it should open immediately if you dropped it into a pan of boiling water. If it opens, stick it back in. I've had nothing but trouble with new engine thermostats that were supposed to open at 88 degrees, only to start opening and then stay stuck open at 120 degrees (dropped in a paint can and heated with a gas axe). I tested four themostats, none of which opened at 88 degrees, only one of which opened at just below 100 degrees! They were allmakes 4x4 stats. I then got my hands on a 'waxstat' and it opened at 89 degrees. The britpart one didn't open at all.

you can see my pipes sat over the steering box here - http://www.landyzone.co.uk/lz/f16/what-difference-106501.html

If you copy the 2nd pic and zoom in you can see the pipes and housing adaptors

Bloody hell they're just a bit expensive

I'll check out a few TD's tomorrow morning to see if there are some kicking about. Looking at the pictures of those pipes on lrseries, they look like they could be made at home with a bit of rubber pipe and some jubilee clips

Yea Thermostate I'd probably go genuine they is only a few quid.

If you do find some dont forget the adaptors

BUT
if you have the stat extention on the filter housing , the disco pipes screw into the housing without the adaptors ( but are too short ) --- if your gonna use the TD pipes you WILL need the adaptors as the pipe ends are different but they screw onto the 200 rad

.

if that makes sence ?

I think I understand. So are you saying that if I use the TD pipes, I will need to fit adaptors to the filter housing (2 adaptors in total) but the pipes will mate with the radiator?

thats the jist I got Pos

pos · May 15, 2010

Well I know what I'm doing tomorrow then! I've got a siren box to fit, an oil catch tank to fit, and possibly even an oil cooler to connect up. Fun fun =)

jai_landrover · May 15, 2010

I wish thats all I had to do tomorrow. I got a cv joint to do, passenger seat to refit, seat belts to fit, floors to put back in, a hand brake to adjust, full service, pick up a trailer and swap over my tyres for a comp on Sunday.

I was never sure the oil cooler in the radiator was up to much and after getting a laser thermometer it proved I was right - negligible temp drop between inlet and outlet.

So I have fitted a standard 13 row oil cooler in series and the difference now is around 9 degrees.

Also once fitted I have moved down to 0W 30W full synth oil and with the new oil cooler the pressure has actually gone up by around 4psi.

Here are some pics - well worth doing and not very expensive - all in about £100 for the cooler, brackets and pipes.
